As you know, I am behind Network Virtualization from the day one of Windows 2012. In the initial days, the information I got is that we don’t need any additional component for enabling network virtualization. But when we tried to test it out, it became clear that the key component to network virtualization successful is Network Virtualization Gateway.
For some reason, I felt like I was searching for a product which was never existing and in the grooming stage. The first positive I got was from Iorn Networks that they had a Virtualization gateway readily available. And later, I noticed that F5 got the Network Virtualization gateay ready along with F5 Big IP Local Traffic Manager. Currently, Network Virtualization Gateway for F5 LTM is only available in the virtual edition and appliance is expected for Q1 2014.
Though we had all these information about third party Network Virtualization Gateways, We missed out Microsoft Network Virtualizaiton Gateway. Microsoft named this product as Windows Server Gateway and is coming up with Windows Server 2012 R2.
Its basically a Virtual Server running on HyperV which can route the traffic between virtualized network and non virtualized network.
I am evaluating both F5 LTM and WSG. Will keep you updated once I have more information.
